Specification of Letters Patent.

Patented Feb. 8, 1921.

Application filed March 4, 1920. Serial No. 363,229.

T 0 all whom it may concern:

Be it known that I, ALONZO E. RHoAnEs, a citizen of the United States,residing at Hopedale, in the county of \Vorcester and State ofMassachusetts, have invented an Improvement in Builder-Motions forSpinning or Winding Machines, of which the following description, inconnection with the accompanying drawings. is a specification. likecharacters on the drawings representing like parts.

The invention to be hereinafter described relates to yarn spinning orwinding machines, and more particularly to the means whereby a bunch maybe produced upon the bobbin or bobbins during the spinning or windingoperation.

In laying or winding the yarn upon bobbins for subsequent use in theloom, it is sometimes desirable to provide a few preliminary windings onthe bobbins before commencing the regular or service wind. Thesepreliminary windings are generally known in the art as a bunch, and thisbunch may be provided to operate a feeler, or it may be provided to givethe lower end of the wound bobbin the desired configuration.

The bunch should be laid by a different traverse of the yarn from thatof the regular or service wind, and upon completion of the bunch it isdesirable that the regular or service wind shall be automaticallyresumed. It is also important that the traverse for the bunch be madeeffective when the spinning or winding operation is started; and withthese generally stated facts in view, an important feature of thepresent invention consists in providing mechanism for imparting atraversing movement to the ringrail in such a manner that a bunch of thedesired configuration will be formed, after which the ring-rail will beautomatically traversed in a manner causing the yarn to be laid upon thebobbin spindle in accordance with the desired regular traverse.

Another important object of the present invention is to provide novelmechanism for building the bunch upon the bobbin in such a manner thatthis bunch will extend along the bobbin spindle a less distance than thebunches heretofore commonly produced, whereby a relatively small amountof yarn is consumed in forming the bunch in the present device.

Another object of the invention is to provide novel means for renderinga bunch building mechanism inoperative upon completion of the bunch.

A further object of the present invention consists in providing means tocoiiperate with the builder arm to thereby relieve the pivot upon whichthis arm is mounted. from lateral strains. And still another object ofthe invention is to provide means whereby the gears for operating thelet-0H mechanism upon the builder arm may be readily moved out ofoperative engagement with each other.

Other features of the invention, in addition to the above, will behereinafter described in connection with the accompanying drawingshowing a good. practical form thereof. it being understood that detailsmay be varied within the true scope of the invention as definitely setforth by the claims.

The invention is herein illustrated as employed in connection with aring-spinning machine, and while it is particularly well adapted to thistype of machine. it is to be understood that it may be employed withadvantage in other types of spinning or winding machines.

In the drawings Figure 1 is a perspective view of a portion of aspinning frame showing the invention applied thereto;

Fig. 2 is an enlarged side view of the builder arm and mechanism mountedthereupon;

Figs. 3 and 4 are side and plan views respectively, of the gearpositioning mechanism carried by the builder arm;

Fig. 5 is a plan view of a detail of the invention;

Fig. 6 is a side view of a bobbin spindle, showing in section theposition of the yarn wound thereupon.

The machine frame for supporting the operating parts may be of any usualconstruction. and as typified in the present illustrated form of theinvention, is of the usual type of ring-rail spinning frame, andcomprises the end frames 10 connected by the longitudinal rail 11. Thisspinning frame may be provided with the spindle rail 12 upon which aplurality of spindles ma be mounts ed, one of which is indicated 13; andabove this spindle rail is mounted the ringrail 1-1 carrying anypreferred number of rings, one of which is indicated at 15. The

spindle 13 is shown as provided with a whirl 16 which is adapted to bedriven by a belt 17 passing around the drum 18. In order that thering-rail may be traversed to thereby properly position the yarn uponthe bobbin it is raised and lowered by lifter 24. All of the mechanismso far described is old and well known in the art, and operates in awell known manner.

Pivotally mounted upon a rigid portion of the spinning frame as at 24 isthe builder arm 25, having a rearwardly-projecting arm 26 carrying aweight 27 upon the rear end thereof. In order to impart the desiredrocking movement to the builder arm, an operating cam 28 is providedhaving any suitable configuration, the particular cam shown beingprovided with four symmetrically formed faces. This cam is rigidlysecured to a shaft 29 which may be 7 driven by any suitable means, notshown, and the faces of said earn are positioned to operatively engage afollower 30 carried by the builder arm, the construction being such thatthe follower 30 is normally held in en gagement with one of the faces ofthe cam 28 by the counterbalancing weight 27. R0- tatably mounted uponthe builder arm adjacent the forward end of the same, is the drum 31,upon the stub shaft 32. This drum is rigidly secured to a gear 33 whichmay be driven by a worm wheel 34 mounted on the pick shaft 35, and uponthe end of this shaft is preferably rigidly secured a ratchet wheel 36positioned to be operated by the actuating pawl 37, connected to aportion of the spinning frame by a rod 38, the construction being suchthat as the builder arm moves in one direction, the pawl 37, which issupported in a predetermined position by the rod 38, will impart thedesired amount of rotation to the ratchet wheel 36. The nadrant 23 isoperatively connected to the rum 31 by a flexible member or chain 39,one end of which passes partway around the drum 31 and may be securedthereto by a screw or the like 40. The flexible member 39 preferablyextends from the drum 31 and passes about a pulley or the like 41rotatably mounted upon a fixed portion of the spinning frame, and fromthis pulley it extends laterally with respect to the builder arm to abolt or the like 42 carried by the quadrant 1 23. The flexible member 39serves to impart the regularor service wind to the ring-rail.

Upon the builder arm at a point nearer the pivot 24 'than the drum 31 isprovided a shaft 43, upon which is rotatably mounted an arm 44, theouter end of which is operatively connected to the bolt 42 by aflexiblemember or chain 45. This arm 44 has a mutilated gear 46 rigidly securedthereto, the same'being rotatably mounted on the stub shaft 43, and theteeth 47 of this gear are positioned to be operatively engaged by a wormwheel 48 secured to a shaft 49 upon the outer end of which is mounted anoperating pinion 50 which is driven by a gear 51 rigidly secured to thepick shaft 35. The builder arm 25 is preferably provided with anupwardly-projecting bracket. 52 upon the outer end of which is rotatablymounted a pulley wheel 53 over which the flexible member 45 passes.

The arrangement of the mechanism so far described is such that when theparts have been properly adjusted to start the winding of the bunch, thetraversing of the ringrail will be controlled by the flexible member 45,while the flexible member 39, which controls the regular traverse, willbe slacked off slightly, as shown in Fig. 1. When the spinning machineis started up, the builder arm will rock up and down in the usual manner, due to the rotating cam 28; and as this arm reciprocates, theratchet wheel 36 will be rotated and will effect rotation of the drum 31by the gear 33 and cooperating worm 34. At the same time, movement willbe imparted to the arm 44 through the gears 51 and 50 and worm 48. Sinceduring the winding of the bunch the traversing mechanism is under thecontrol of the flexible member 45, the slow unwinding of the drum 31 inthe direction indicated by the arrow will have no influence on thetraverse of the ring-rail; but while the bunch is being formed, theouter end of the arm 44 is gradually being swung in an upward directionby the mechanism described, and this upward movement continues until theteeth 47 of the mutilated gear have been moved out of mesh with the worm48, whereupon further rotation of this worm will no longer swing the arm44 about its pivot. As soon as the teeth 47 have become disengaged fromthe worm 48, in the manner just pointed out, the arm 44 will be nolonger held in a position to exert an operating pull upon the flexiblemember45, so that the bunch traversing mechanism will in this mannerbecome inoperative upon the completion of the bunch, whereupon the usualservice traverse Will be imparted to the ring-rail by the flexible'member 39 and mechanism con nected therewith, it being understood that,during this service wind, the drum 31 is slowly unwound to permit theupward movement of the ring-rail to be gradually increased.

An important feature of the bunch-forming mechanism just described isthe arrangement whereby the outer end of the arm 44 is adually swungupward throughout the evelopment of the bunch. This arrangement of partscauses each upward movement of the ring-rail in the production of thebunch, to rise a little higher than the preceding upward traverse, andto move downward] a distance not quite as far as the preceding traverse,whereby the yarn wound upon the bobbin in the production of the bunchwill be deposited upon the bobbin in the manner indicated at 54, Fig. 6.In this fi re, it will be noted that the yarn is place upon the bobbinin successive layers of substantially the same length of traverse, andthat each layer occupies a position slightly nearer the tip of thebobbin than the preceding layers. This particular manner of winding theyarn forming the bunch is desirable, because it produces a bunch whichextends lengthwise of the bobbin a relatively short distance, and whileproviding the requisite initial supply of yarn produces the desired format the base of the wound bobbin.

Due to the fact that the builder arm 25 is provided with an upwardlyprojecting bracket 52 carrying a pulley wheel over which the flexiblemember 45 passes, a considerable strain will be exerted upon the pivot24 of the builder arm unless means is provided to relieve this strain.There is therefore provided an upwardly-projecting arm 55, the lower endof which is rigidly secured to a suitable portion of the spinning frame,and the upper end of the bracket 52 is provided with an anti-frictionroller 56 positioned to rest against the said arm 55 throughout thereciprocation of the builder arm.

In order that the parts may be readily restored to the position whichthey should occupy at the beginning of the winding operation, means isprovided by which the outer end of the shaft 49 may be manually swungaway from the pick shaft 35; and in the embodiment of the inventionshown, an eccentric member 57 is provided about the shaft 49, whichmember is rotatably mounted in the outer end of the builder arm 25. Theeccentric member 57 is provided with a projecting arm 58 having alaterally-extending lug positioned to rest upon the finger 59 formedintegral with the builder arm 25 while the gears are in mesh with eachother. This eccentric member permits the gears to be readily moved outof mesh with each other by swinging the arm 58 upwardly, as shown inFig. 3. whereupon a wrench or the like may be inserted in the squaresocket formed in the outer end of the shafts 35 and 49, to rotate theseshafts and thus restore the members operated thereby to the desiredposition. After the arm 4-4 has been swung upwardly to the positionshown in Fig. 2,

in which the worm 48 is out of mesh with the teeth 47, it is desirableto provide means for retaining the parts in the position shown in thisfigure, so that as soon as the worm 48 is rotated manually in adirection to swing the arm 44 downward, the teeth 47 will be immediatelyengaged by the worm; and for this purpose the coiled spring 59 is coiledabout the stub shaft 43, and has one end rigidly connected to thebuilder arm while the other end reacts against the mutilated gear, tonormally hold the same in the desired position.

From the foregoing description read in connection with the accompanyingdrawings, it will be seen that a very simple but effective mechanism isprovided for building a bunch in the manner above pointed out, and thatafter this bunch is completed, the bunch building mechanismautomatically goes out of operation, whereupon the yarn is wound uponthe bobbin spindle in a desired manner to provide the regular or servicewind.
